A 25-year-old man had a right sided cyst-like swelling removed from his forehead. Histology revealed a well circumscribed spindle cell lesion with myxomatous changes. Immunohistochemical staining with muscle markers (smooth muscle actin, muscle specific actin) was positive. The histological features along with the immunohistochemical staining profile are of a leiomyoma with myxoid change arising in the temporal artery. Leiomyomata arising from vessels are extremely rare and to our knowledge this is the first case arising from the temporal artery.
一名25岁男性的前额右侧有一个囊肿样肿物被切除。组织学检查显示为边界清楚的梭形细胞病变，伴有黏液样改变。用肌肉标志物（平滑肌肌动蛋白、肌肉特异性肌动蛋白）进行免疫组化染色呈阳性。组织学特征以及免疫组化染色结果符合颞动脉发生的伴有黏液样改变的平滑肌瘤。血管来源的平滑肌瘤极为罕见，据我们所知，这是首例起源于颞动脉的病例。
